Avatar: 9 of 10. It's a happy little Demon Monkey.
Signature: 4 of 10. I can't remember that Tekken character's name, so that's frustrating, and I prefer Blimpie's.
--EDIT--
Signature, revised score: 2 of 10. Upon learning that it is not, in fact even a Tekken character, points are subtracted appropriately.
